About Cracked LCD Screen

By on August 10, 2012

If you read the comments in this the below link you will find out that moast of the time the LCD TV screen cracked on its own and was not due to other reason.

About a month plus ago, I've got an email from a local guy and this was the email:

"Hi Jestine Yong,
I have a problem regarding LCD TV claiming under warranty & I am not sure whether I should contact you or Kent Liew. I need professional consultation or witness   in a consumer tribunal court regarding a damaged LCD screen claim. Allow me to briefly describle what is the issue about. My relative bought a Panasonic LCD TV Model: TH-L42U30K & in a about 1 month the LCD screen was discovered cracked when the power was switch on. The LCD TV was not subject to any external forces & there is no physical damaged or mark on the screen. To my knowledge  LCD panel can crack by itself for quite a number of reasons apart from the external force on the screen. Panasonic claimed that the damaged is caused by external forces on the screen . They will charge labour & LCD screen replacement."

Then last week I got an email from the same guy again, check out the email :

We have won the case & get full refund on the purchase price because of the poor quality of the LCD screen. Panasonic argued that it can be easily damage & they demonstrated it by using a recorded  video on a pc to show how the screen can be easily cracked. The video showed that with a sponge wrapped on the head of a screw driver or test pen the screen will cracked instantly when you just tap on the screen with the sponge wrapped screw driver head. 
The argument is how can they expect the customer to take care of the tv when the screen is so fragile"


What do you think about the above case? I'm not sure if you have ever came across such LCD TV where the LCD panel broke by itself. If you have any comment on this we would like to hear from you-thanks.
